Imikoreshereze
Aside ya Levuline ni ikintu gikomoka ku bimera kandi ibikomoka kuri yo, nka ethyl levulinate na alkyl levulinate, bishobora gukoreshwa nk'inyongera ku bikomoka kuri peteroli.
aside levulinic ikoreshwa mu gukora levulinate ya kalisiyumu mu miti, nka esters mu bintu bishongesha ibintu no mu byuma bihindura imiterere ya pulasitiki, no mu gukora valerolactone. Uko ikoreshwa, ishobora kuba ikorwa mu myanda ya cellulosic. aside Mesitonic, homologue ya aside levulinic iboneka binyuze mu kubitsa oxide ya mesityl hamwe na KCN.
Gutera aside levuline hifashishijwe hydrogene bishobora gukora izindi miti y'ingirakamaro. Valeric-g-lactone, ikaba ari umuti ukora neza kandi ukoreshwa cyane, ishobora kuboneka mu musaruro mwinshi cyane. Iki kintu gishobora gushyirwamo hydrogene muri 1,4-pentandiol, iyo amazi amaze kubura 1,3-pentadine (piperylene). Piperylene izwiho gukora polymere kugeza ku rugero nk'urwa rubber bityo ikaba isoko y'urubber rwa sintetike (Ghorpade na Hanna 1997).
Aside ya Levuline ni ingenzi mu gukora ibintu by'ingirakamaro nka γ-valerolactone, ethyl levulinate, aside pentanoic na 2-methyl-tetrahydrofuran. Guhindura no gupima aside ya levuline bivamo ibikomoka kuri peteroli bishobora gukoreshwa.
Ishobora kandi gukoreshwa muri:
Gutegura imvange ya catalytic yo gukora 5-hydroxymethylfurfural na furfural.
Gukora impumuro nziza ikoreshwa mu bucuruzi, fraistone.
Gukora ikorwa ry'ibikomoka kuri pyrrolidone binyuze mu gutuma igabanuka ry'umusemburo rigabanuka.
Ikorwa ry'ibinyabutabire bya mycobacterial arabinogalactan.
Gupfunyika
200KG/Ingoma cyangwa nk'uko umukiriya abikeneye.
Bika kandi ubibike
Igihe cyo kubika: Amezi 24 uhereye igihe byakorewe mu ipaki y’umwimerere idafunguye, bibitswe ahantu hakonje kandi humutse, kure y’izuba ryinshi, amazi.
Ububiko bufite umwuka uhagije, Butuma ibintu bishya bishyuha, butandukanyijwe n'ibikomoka kuri okiside, aside.
